BACKGROUND/OBJECTIVES: Nutrition is a determinant factor of health in elderly people. Independent living in elderly people can be maintained or enhanced by improvement of nutritional behavior. Hence, the present study was conducted to determine the impact of Health Belief Model (HBM)-based intervention on the nutritional behavior of elderly women.
SUBJECTS/METHODS: Cluster-random sampling was used to assess the sample of this clinical trial study. The participants of this study attended a 12-week nutrition education program consisting of two (2) sessions per week. There was also a follow-up for another three (3) months. Smart PLS 3.5 and SPSS 19 were used for structural equation modeling, determination of model fitness, and hypotheses testing.
The findings indicate that intervention had a significant effect on knowledge improvement as well as the behavior of elderly women. The model explained 5 to 70% of the variance in nutritional behavior. In addition, nutritional behavior was positively affected by the HBM constructs comprised of perceived susceptibility, self-efficacy, perceived benefits, and barriers after the intervention program.
The results of this study show that HBM-based educational intervention has a significant effect in improving nutritional knowledge and behavior among elderly women.
背景/目的:营养是老年人健康的一个决定性因素。通过改善营养行为可以维持或增强老年人的独立生活能力。因此,本研究旨在确定基于健康信念模型(HBM)的干预对老年女性营养行为的影响。
受试者/方法:采用整群随机抽样来评估这项临床试验研究的样本。本研究的参与者参加了一个为期12周的营养教育项目,每周有两节课。此外还有为期三个月的随访。使用Smart PLS 3.5和SPSS 19进行结构方程建模、模型拟合度测定和假设检验。
研究结果表明,干预对老年女性的知识提升和行为有显著影响。该模型解释了营养行为中5%至70%的方差。此外,在干预项目后,由感知易感性、自我效能感、感知益处和障碍组成的HBM结构对营养行为产生了积极影响。
本研究结果表明,基于HBM的教育干预对改善老年女性的营养知识和行为有显著效果。
